Conformation describes a convention for working with partial parity bonds (BBPs). It assumes that bonds are encoded left-to-right. In other words, target always succeeds source.
This works under the assumption that the graph has no cycles. If one exists, then the edge that bites back can be forward (target succeeds), reverse (target precedes), or both. This case leads to incorrect selection of neighbor quadrant.
Whatever solution is chosen must account for the apparent dual state of the central PPB in hexadiene (C/C=C/C=C/C).
Options:
reverse assignment in the event that target precedes source
